12)
number of electron in bonding orbital = 8
number of electron in anti bonding orbital = 2
Bond order = (1/2)*(8-2) = (1/2)*6 = 3
since all electrons in molecular orbital are in pair, it is diamagnetic in nature
13)
C has 6 and O has 8 electron
Total electrons in CO = 6+8 = 14
N has 7 and O has 8 electron
Total electrons in NO = 7+8 = 15
NO+ has 15-1= 14 electrons
So, number of electrons is same for NO+ and CO
So, molecular orbital will also look same
Hence bond order will also be same
Bond order = 3
